Application filed August 9, 1918. Serial N 0. 249,162.

To all whom, it may concern.-

Be it known that I, WILLIAM HENRY ARTYN, a subject of the Britain andIreland, residing at Cowper street, Tenterfield, State of New SouthWales, Commonwealth of -Australia,have invented new and usefulimprovements in appliances for automatically governing the feed offuel-oil to internal-combustion engines of the type in which thecylinders rotate, of which the following is a specification.

This invention is specially adapted to that class of internal combustionengines in which the cylinders'rotate. In giving efl ect to theinvention the appliance may be attached to the heads of'the cylinders,or in any other position as near as possible to the point of combustionof the fuel, provided that the attachment be madeto that rotates. In itssimplest form the appliance consists of a small casting inserted in theline of the feed and transversely across this line is mounted thecylindrical governor against the outer end of which abuts a helicalspring in compression. When the speed 15 too great the cylindricalgovernor will be thrown outward, bycentrifugal force, against theresistance of the spring, thus partly, or entirely, closing the passagethrough which the fuel is fed.

A is a casting that will beinserted in the fuel feed passage at anysuitable point; B is the line along which the fuel is fed; transverselacross the fuel feed passage B is a cylin rical chamber 0 that isadapted to contain the governor D, which consists of a cylindrical blockof metal that makes an easy fit with the wall of the cylindrical chamberC. The block D is maintained in its normal position by a helical springE that will be inserted through the open end of the casting, which willbe closed by a screw plugF that will also serve as a means of adjustingthe compression of the spring'E. The overnor block D will, normally,cover the uel passage B, but there will be an annular groove King ofGreat a part of the engine ernor be rendered said bore and having Gnormally in' line with the passage B through whichfuel can normallypass; but when centrifugal force operates causing the block D to moveoutward, the annular passage G will move outward, the part of the blockbelow it partially or wholly closing the In engines where the velocityis very high,

it will be advisable, in order that the govmore sensitive, that theinstallation of the appliance be not in the vertical plane of rotationof the engine, but at an angle thereto, as indicated by the dottedlines.

1. A device of the class described comprising a casing formed with afuel-feeding passage and a bore intersecting said passage between theends thereof,a block movable in a longitudinally extending bore anda'groove formed therein, said groove being adapted to register with thefuel passage, and means for biasing said block to a posltion whereinsaid groove registers with said fuel passage.

2. A device of the class described comprising a casing formed with afuel-feeding passage and a bore extending transversely and intersectingsaid passage between its ends, a block movable in said bore and having agroove formed therein ada ted to register with said passage, means orbiasing said block to a predetermined position, and a spring-pressedvalve in said passage for preventing back-pressure therein.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
